Spraying epsom salt on plants boosts magnesium supply to plants and increases yield. GARDEN HACK: How to start maintaining your garden. Spraying 1 table spoon of epsom salt mix with 4 litre of water twice with 10 days gap could be used for good results. Use for growing tomatoes, peppers and roses
For potted plants, mix a couple of tablespoons of the salt into your watering can once or twice a month. You can also sprinkle it in your garden’s soil to help your seeds germinate better. Tomatoes and peppers benefit the most because they both tend to have a magnesium deficiency. Add a tablespoon or so in with the soil when first planting, and then sprinkle more into the soil once mature.
